IMPROVEMENT IN WEATHE R-STRI PS.

Specification forming part of Letters Patent No. 197,843, dated December4,1877; application filed August 3, 1877.

To all whom it may concern:

Be it known that we, MELVIN FRINK and J AMES FRINK, both of Farmington,.in the county of St. Francois, in the State of Missouri, have invented anew and Improved Weather-Strip; and we do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

Our invention relates to devices for excludin g cold or drafts of airfrom dwellingrooms'; and it consists in the construction and arrangement of an improved so-called weather-strip, made in two parts, onefitting into the other when the door or shutter to which our improvementis applied is closed, substantially as hereinafterinore fully described,andpointed out in the claims.

In the drawings, Figure l is a perspective view, showing the applicationof our invention to the under side of a door; and Fig. 2. is allverticalsection of the door, strip, and doors' l.

Similar letters of reference indicate corresponding parts in both thefigures.

A is the door, B B the door-posts, and c the sill. Pivoted in each ofthe posts, near the bottom, is a flat metal strip or plate, I), whichprojects forward over the sill, and has a rubber strip, 0, narrower thanitself, inserted under it, so that plate 12 will overlap strip 6, as Tothe under side of the doorA is secured another metal strip or plate, a,the ends of which are bent up over the lower corners of the door, andheld in place by. screws or brads, so as to leave an open space orrecess between the under side or edge of the door and strip a, intowhich is inserted a narrow rubber strip, (Z.

connection with the drawings, the operation of our invention will bereadily underst00d:"

When the door or shutter is closed, as in Fig. 2, strip a will enter therecess between plate I: and the sill, compressing the rubber strip orpacking e and forming a tight joint. In like manner plate I) will enterthe recess below the edge of the door, and form a tight joint with thepacking d, so that it will be absolutely impossible for drafts of air topass in under the door.

Plate a may, if desired, be made twice the width of plate I) anddoubled, the packing. strip d being inserted into the recess formed bydoubling it; but this is not necessary unless the open space between theedge of the door and the sill is unusually large.

It is obvious that our invention is applicable to hinged doors,shutters, or windows of all kinds, and that it may be used at the sidesand top as well as at the bottom.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States 1. The combination of the sill c,packingstrip 0, and overlapping hinged plate [1, substantially as andfor the purpose herein shown and specified. v

2. In combination with the sill 0, having packing e-and hinged strip 11,the doorA, having plate a and packingstrip, d, substantially as and forthe purpose herein shown and specified.
